The theses tries to come to terms with the ongoing processes of deterritorialisation and sectoralisation of politics. Already new modes of transnational governance have been established while the concept of democracy is still connected to the nation-state and forms of representative government. Therefore the theses examines the social conditions of the development of ‘transnational sectoral demoi’ – arguing in favour of a frame- and codetheoretical reconceptualisation of the public space. On that basis a certain proposal is given how the political sociology of the European Union can be identified and analysed avoiding the shortcomings what is known as the politics of identity and the rule of experts.
